In some embodiments, the ostomy-bag cover is constructed such that the patient can engage in water related activities, including swimming, while wearing the ostomy-bag cover over the ostomy bag and prevent the ostomy bag from getting wet. In some embodiments, the ostomy-bag cover includes a resealable opening configured to allow the patient to empty the ostomy bag without the need to remove the ostomy-bag cover. In other embodiments, the ostomy-bag cover includes a waterproof exhaust vent to allow air to be removed from the ostomy-bag cover.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation-in-part of U.S. patent application Ser. No. 13/018,210 titled “OSTOMY BAG WATERPROOF COVER AND METHOD” filed Jan. 31, 2011 (which issued as U.S. Pat. No. 8,377,020 on Feb. 19, 2013), which claimed priority to U.S. Provisional Patent Application No. 61/434,348 titled “OSTOMY BAG WATERPROOF COVER AND METHOD” filed Jan. 19, 2011, both of which are hereby incorporated herein by reference in their entirety.

FIELD OF THE INVENTION

The invention relates generally to ostomy bags and, more specifically, to covers for ostomy bags that can protect an ostomy bag during bathing or other activities.

BACKGROUND OF THE INVENTION

An ostomy is a surgical procedure in which an opening is created in a body for the discharge of waste. In this procedure, a passageway or stoma is made, typically through the abdominal wall and skin of the patient, and a portion of an intestine is surgically connected to the stoma so that waste matter can exit the body.

As used herein, “ostomy” is intended to cover all types surgical procedures in which a stoma is formed through the skin and is connected to an internal organ. Two common ostomies are “colostomy” wherein the colon is connected to the stoma, and “ileostomy” wherein the small intestine is connected to the stoma. Waste matter (fecal material) is uncontrollably discharged from the stoma. Consequently, the patient is required to wear an ostomy appliance, commonly known as an ostomy bag (or a stoma bag), wherein a flange of the ostomy bag is attached to the abdominal wall of the patient with an adhesive, and a plastic waste bag attached to the flange collects the waste discharged by the body. In some embodiments, the plastic waste bag can be removed from the flange and emptied as needed. A wide variety of ostomy bags are in general use.

While ostomy bags effectively collect waste matter, they present a number of problems. The actual collection bags are typically made of a plastic material that is somewhat transparent, which allows the collected waste matter in the bag to be partially visible, and which also has a tendency to stick to the body of the patient and to irritate the patient's skin. Ostomy bag covers have been designed to address these modesty and discomfort problems.

A generally rectangular cutout in the guard is sized and oriented to surround the protective bandaging and leave a margin between the edge of the cutout and the protective bandaging so that the bandaging will not be disturbed when the guard is removed.

U.S. Pat. No. 2,815,883, which issued to Robins et al. Dec. 10, 1957 titled “Spirally Wound Covering For Popcorn Containers,” is incorporated herein by reference. Robins et al. describe a cover for packages which is so constructed whereby it occupies a relatively small space when placed on a container and will open to greatly increase the effective size of the container. Robins et al. describe, in relation to prior-art FIGS. 3H to 3M, as follows: Referring now to prior-art FIGS. 3H through 3M, inclusive, it will be seen that there is illustrated the steps in forming the cover 28. Initially the cover 23 is in the form of a flat sheet of material 40 which is preferably square and formed of aluminum fob, although other desired materials may be utilized. In order to shape the cover 28 to meet the shape of the container 12 and at the same time to hold the sheet 40 in place during the cover forming operation, there is provided a pattern forming retainer 42. The retainer 42 is in the form of a flat plate. 44 which has a central circular opening 46 which is the pattern for making the cover 28. Referring now to FIG. 3M in particular, it will be seen that there is Illustrated a forming member which is referred to in general by the reference numeral 48. The forming member 48 includes an inverted cup-shaped portion 50 which has extending upwardly therefrom a shank 52. The upper end of the shank 52 terminates in a handle 54. After the pattern forming retainer 42 has been positioned as illustrated in FIG. 3 i, the forming member 48 is positioned in the exact center of the opening 46. With pressure being applied simultaneously to the pattern forming retainer 42 and to the forming member 48, the forming member 48 is rotated through a slight angle. This results in the twisting of the central part of the Sheet 40 about the forming member 48, as is best illustrated in FIG. 3J. As the sheet 40 is twisted, the spiral folds 32 are simultaneously formed. Inasmuch as the folds 32 are tightly turned about the forming member 48, when the forming member 48 is lifted from its position in FIG. 3J, the central portion 30 is pulled upwardly out of the plane of the outer part of the sheet 40. Thus, when the pattern forming retainer 42 has been removed, the central portion of the sheet 40 which will become the cover 28 is slightly upwardly bowed. After the pattern forming retainer 42 has been removed from the sheet 40, a suitable die (not shown) is utilized to cut the cover 28 of a size to fit from the sheet 40.

There is a need for an improved ostomy bag cover.

DETAILED DESCRIPTION OF THE INVENTION

Although the following detailed description contains many specifics for the purpose of illustration, a person of ordinary skill in the art will appreciate that many variations and alterations to the following details are within the scope of the invention. Accordingly, the following preferred embodiments of the invention are set forth without any loss of generality to, and without imposing limitations upon the claimed invention. Further, in the following detailed description of the preferred embodiments, reference is made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration specific embodiments in which the invention may be practiced. It is understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention.

The leading digit(s) of reference numbers appearing in the Figures generally corresponds to the Figure number in which that component is first introduced, such that the same reference number is used throughout to refer to an identical component which appears in multiple Figures. Signals and connections may be referred to by the same reference number or label, and the actual meaning will be clear from its use in the context of the description.

As used herein, the term “ostomy appliance,” the term “ostomy bag” and the term “stoma bag” are synonymous. As noted above, an ostomy bag typically has a flange that is attached to the abdominal wall of the patient with an adhesive, and a plastic waste bag, attached to the flange, that collects the waste discharged by the body. In some embodiments, the plastic waste bag can be removed from the flange and emptied as needed, and then reattached to the flange for reuse.

As used herein, the term “waterproof” means keeping an item completely dry for a period of at least 60 minutes while submerged in water or exposed to water spray. As used herein, the term “watertight” means keeping an item dry for at least at least 30 minutes while exposed to water spray and at least 5 minutes while submerged in water. As used herein, the term “water-resistant” means keeping an item dry for at least 15 minutes while exposed to casual water contact, such as water spray in a shower.

As used herein, the term “band” means the substantially flat area of material between two geometric shapes, such as the area of material between two substantially concentric circles (also known as an annulus), the area of material between two substantially concentric ovals, the area between two substantially concentric rectangles, the area of material between two substantially concentric rectangles with rounded corners, the area of material between a circle/oval and a square/rounded square, or between any two geometric shapes where the inner shape is the edge of the material that surrounds an opening and the outer shape is the other outside edge of the material that surrounds the inner shape. The term “band” also includes the flat area of material between two geometric shapes where the shapes are not substantially concentric such as is the case when one side of the band is wider than another side of the band (i.e., wherein the opening is not centered within the material).

Problems are encountered with ostomy bag usage when showering. A person can do any of several things with the ostomy bag when he or she showers: the patient can wear the ostomy bag, getting it wet. The ostomy bag needs to be dried or changed after the shower to prevent moisture against the skin, causing possible chafing and skin irritation. Persons can use a hair dryer to dry the external bag. The hot air from the hair dryer causes the ostomy-bag flange adhesive as well as the fabric of the bag to wear out prematurely. Some people wash and dry the original stoma bag for reuse.

A person can remove the bag before the shower. If the person chooses to use nothing as a bag, then the excrement can flow freely during the shower and is messy and unsanitary.

In some embodiments, the present invention includes a one-piece waterproof impermeable stoma-bag cover with a flange having a very flexible flange edge for better sealing capability. The impermeable plastic stoma-bag cover encloses the fabric stoma bag and the stoma bag's flange, and the flange of the stoma-bag cover is adhesively attached to the skin surrounding the flange of the stoma bag. The impermeable stoma-bag cover fits over the various styles of stoma bags and their flanges. In some embodiments, the impermeable stoma-bag cover and the cover's flange form a single unit that comes in two sizes, one for children and one for adults. After showering, the person typically removes and disposes the impermeable cover and flange. The impermeable stoma-bag cover of the present invention, with its flange, is convenient and efficient to use. Use of the stoma-bag cover minimizes the time it takes the person having a stoma bag to get ready after showering (since it is not necessary to change or dry the original stoma bag and flange); minimizes wear and tear and extends the life of the original stoma bag and its flange because it is no longer necessary to dry the original stoma bag and flange. The stoma-bag cover keeps the stoma bag dry. Use of the stoma-bag cover allows less frequent changing of the original stoma and flange, which reduces chance of skin irritation. Use of the stoma-bag cover removes some of the risk of a possible leakage that can happen when water or heat are used on the stoma bag's flange.

In other embodiments, the present invention includes a water-impermeable cover. The water-impermeable cover has a non-irritating adhesive around the open circle on the back side which adheres to the left or right side of abdomen. In some embodiments, the water-impermeable cover has optional flaps along sides to be placed over the navel (umbilicus). This is to be used if the edge of the impermeable bag ends up close to the navel, in that case the flap is put over the navel to seal off any chances of water getting into the navel and then leaking into the bag. If a person does not need the flap, the flap can be cut off.

In some embodiments, the present invention includes a waterproof cover that surrounds the ostomy bag as well as the ostomy bag's flange in one easy step, wherein the cover is a one-piece bag and adhesive flange. Attributes of the cover include:

A. One doesn't have to change stoma bags and flanges as often because the water proof bag keeps it all dry. The appliance (stoma bag) lasts longer when the flange does not get wet.

B. One doesn't have to shower without one's appliance. This eliminates having to clean up an unsanitary bathtub after a shower.

C. One saves time and there is no mess since one is not changing one's stoma appliance.

D. One will save money by not having to change one's appliance as often.

E. There will be less skin irritation due to less stoma appliance changes per week.

F. It is disposable, making it quick and easy to use and throw away.

G. It is affordable, being much less expensive than a replacement stoma bag.

H. The stoma bag flange stays dry so one doesn't have to use hairdryer to dry the stoma bag flange after showering. This saves a lot of time getting ready for the day.

I. It allows for easy, quick daily showering.

J. It is convenient.

K. It is simple to put on.

L. One doesn't have to wash the stoma bag out for reuse.

The flange 211 removeably attaches to the abdomen of the patient 99 with an adhesive on the proximal side of the flange 211 wherein the seal formed by the flange and the skin of the patient is substantially watertight. Further, in other embodiments of the present invention, a tab 218 is attached to the ostomy-bag-cover flange 211 such that the tab 218 is used to cover and seal the perimeter of the area around the navel 98 of the patient 99 when the stoma is located near the navel such that ostomy-bag-cover flange 211 may not adequately seal all of the perimeter of the area around an ostomy bag (not shown) due to the uneven surface of the skin in the proximity of the navel. If not needed, the ostomy-bag-cover tab 218 can be removed, either by cutting it off, or in some embodiments, torn along perforations at the connection of the tab and the ostomy-cover flange 211. The ostomy-bag cover 200 keeps water away from the ostomy bag (not shown) so that in some embodiments, the patient can shower or bathe without getting his or her ostomy bag wet. In some embodiments, the ostomy-bag cover is single-use, and is removed and disposed of after the patient bathes or showers.

FIG. 3A is a front perspective view and FIG. 3B is a side perspective view of an ostomy-bag cover system 300, according to other embodiments of the present invention. The ostomy-bag cover 300 includes a flange 311 and a liquid-impermeable flexible cover 316. In some embodiments, the liquid-impermeable flexible cover folds flat (such as shown in FIGS. 3H through 3M) for packaging and distribution, and unfolds to cover an ostomy bag (not shown). In some embodiments, this unfolding can be similar to that used in “Jiffy Pop” package tops, as described in U.S. Pat. No. 2,815,883 to Robins et al. issued Dec. 10, 1957 titled “Spirally Wound Covering For Popcorn Containers”.

In some embodiments, the ostomy-bag-cover flange 311 includes an inner region 312 and an outer region 313, wherein the flange inner region 312 is attached to the liquid-impermeable flexible cover 316 and the proximal (patient-skin) side of the flange 311 is coated with an adhesive that releasably fastens the ostomy-bag cover to the abdominal skin of the patient 99. The ostomy-bag cover when attached to the patient forms a substantially watertight covering over the ostomy bag.

FIG. 3C is a top cross-sectional view and FIG. 3D is a back view of the ostomy-bag-cover system 300, according to some embodiments of the present invention. In other embodiments, the ostomy-bag-cover flange 311 is coated with an adhesive that releasably fastens the ostomy-bag cover to the abdominal skin of the patient 99, forming a watertight seal between the flange 311 and the skin of the patient 99. In some embodiments, the adhesive coated flange is protected with at least one thin, easily removable layer of material during shipping to prevent the flange adhesive from adhering to anything prior to being attached to the patient's skin. In some embodiments, the protective material can be paper. In other embodiments, the protective material can be plastic or other thin film. To attach the ostomy-bag cover, the patient first removes the protective layer 341 from the inner region of the ostomy-bag-cover flange 311, and then positions the ostomy-bag cover in the desired location on his or her abdominal skin. The adhesive on the inner region of the flange holds the ostomy-bag cover to the patient's skin and aids in the positioning of the ostomy-bag cover. Once the ostomy-bag cover is positioned as desired, the protective layer 342 from the outer region of the flange 311 is removed and the flange is firmly pressed onto the patient's skin, forming a watertight seal. In the process of attaching the ostomy-bag cover, the ostomy-bag cover may have to be repositioned one or more times, or may flex in handling, resulting in wrinkles in the flange and possibly areas on the flange where the adhesive has become weak. In such cases, the needed watertight seal between the flange and the skin of the patient may be compromised. The adhesive on the outer region of the flange, which is not exposed until the ostomy-bag cover is positioned on the patient's skin, ensures a good seal between the flange and the skin. In some embodiments, each ostomy-bag cover is enclosed in its own wrapper 345 made of, e.g., paper, cardboard, plastic, foil and/or the like.

In some embodiments, each of the protective layers 341 and 342 is a single piece of material. In other embodiments, either or both of the protective layers is formed from two pieces of material as shown in FIG. 3D. This allows the layer of protective material to be more easily removed, especially the layer of protective material 342 that covers the outer region of the flange, since this layer of protective material is removed after the ostomy-bag cover is partially attached to the patient's abdominal skin with the adhesive on the inner region of the ostomy-bag-cover flange. In some embodiments of the present invention, the ostomy-bag-cover flange 311 is one centimeter wide. In other embodiments, the ostomy-bag-cover flange 311 is wider than one centimeter. In other embodiments, the ostomy-bag-cover flange 311 is narrower than one centimeter. In some embodiments, each ostomy-bag cover is enclosed in its own wrapper 345 made of, e.g., paper, cardboard, plastic, foil and/or the like.

The ostomy-bag cover 300 keeps water away from the ostomy bag (not shown) so that in some embodiments, the patient can shower or bathe without getting his or her ostomy bag wet. In some embodiments, the ostomy-bag cover is single-use, and is removed and disposed of after the patient bathes or showers.

In other embodiments of the present invention, only the outer protective layer 342 is removed prior to attaching the ostomy-bag cover to the abdominal skin of the patient. After showering or bathing, the patient removes the ostomy-bag cover and keeps it for a second use. For the second use of the ostomy-bag cover, the inner protective layer 341 is removed prior to attaching the ostomy-bag cover to the abdominal skin of the patient. The ostomy-bag is then removed and disposed of after the patient bathes or showers.

FIG. 3E is a top cross-sectional view of an ostomy-bag cover system 300. In some embodiments, at least a first layer of protective material 343 and a second layer of protective material 344 cover the ostomy-bag-cover flange 311. The proximal (patient-skin) side of the flange 311 is coated with an adhesive that releasably fastens the ostomy-bag cover to the abdominal skin of the patient 99. The first layer of protective material 343 covers and protects the adhesive on the proximal (patient-skin) side of the flange 311, and the proximal side first layer of protective material 343 is coated with an adhesive that releasably fastens the ostomy-bag cover to the abdominal skin of the patient 99. The second layer of protective material 344 covers and protects the adhesive on proximal side of the first layer of protective material 343. In use, the second protective layer 344 is removed, exposing the adhesive on the proximal side of the first protective layer 343, and the ostomy-bag cover is attached to the abdominal skin of the patient. After showing or bathing, the ostomy-bag cover is removed for later reuse. For a second use, the first protective layer 343 is removed, exposing the adhesive on the proximal side of the flange 311, and the ostomy-bag cover is attached to the abdominal skin of the patient. After the second use, the ostomy bag cover can be disposed of.

In some embodiments, the ostomy-bag cover kit includes an ostomy-bag cover body 360 and an adhesive-attachment band 350, wherein the adhesive-attachment band is shaped substantially the same as the ostomy-bag-cover flange 311. The adhesive-attachment band has a first surface which is coated with an adhesive and a second surface which is coated with an adhesive, and releasably fastens the ostomy-bag cover to the abdominal skin of the patient 99. A first layer of protective material 351 covers and protects the adhesive on the first surface of the adhesive-attachment band and a second layer of protective material 352 covers and protects the adhesive on the second surface of the adhesive-attachment band. In some embodiments, each of the protective layers 351 and 352 is a single piece of material. In other embodiments, either or both of the protective layers are formed from more than one piece of material as shown in FIG. 3F. In some embodiments, the adhesive-attachment band 350 is constructed from a polymer film or polymer foam. In other embodiments, the adhesive-attachment band is constructed from paper. In some embodiments, the layers of protective material 351 and 352 can be paper. In other embodiments, the layers of protective material 351 and 352 can be plastic or other thin film.

In use, the patient removes the first layer of protective material 351 from the first surface of the adhesive-attachment band 350 and places the adhesive-attachment band on his or her abdomen in the appropriate location around the ostomy-bag flange. Then the patient removes the second protective layer 352 on the second side of the adhesive-attachment band and attaches the ostomy-bag-cover flange to the adhesive-attachment band forming watertight seal between the ostomy-bag cover and the patient's skin.

In some embodiments, the ostomy-bag-cover flange 411 is sized so that there is uncovered patient skin 430 between the ostomy-bag-cover flange 411 and the ostomy-bag flange 81. When an ostomy-bag cover is attached to a patient, the ostomy-bag cover and the adhesively formed seal result in a completely or nearly completely waterproof covering for the patient's ostomy bag. In some embodiments, the water impermeable plastic bag cover 416 includes a waterproof one-way vent 417 that allows air or other gases to be expelled from inside of the sealed ostomy-bag cover without the need to remove the ostomy-bag cover. This commonly referred to as “burping” the bag. In other embodiments, the water impermeable plastic bag cover 416 includes a watertight resealable opening 414, through which the ostomy bag 80 can be emptied without removing the ostomy-bag cover. In some embodiments, the resealable opening is a zipper-style closure such as the type found on resealable ziplock plastic bags. In other embodiments, the opening is sealed with a clip or other fastener wherein the patient can unclip and unroll bottom of waterproof bag, pull out the ostomy bag from inside, empty the ostomy bag, and then roll water impermeable plastic bag cover and clip it to reestablish the watertight seal. In other embodiments, the opening is sealed with a Velcro® closure.

In some embodiments, the water impermeable material of plastic bag 416 is of sufficient strength and durability, such as a heavy gauge plastic, to permit the patient to swim with the ostomy-bag cover 400 in place, attached to the skin of his or her abdomen. This allows the patient to swim or engage in other wet activities without getting his or her ostomy bag wet.

In some embodiments, the ostomy bag cover 400 includes tabs 418 and 419 used to cover the navel of the patient 99 if the navel is an area near the outer region of the ostomy-bag-cover flange 413. The appropriate tab is used depending of which side of the body the stoma is located, wherein the unneeded tab can be removed. Both tabs can be removed if neither is needed.

FIG. 5A is a front perspective view and FIG. 5B is a side perspective view of an ostomy-bag cover system 500 according to some embodiments of the present invention. The ostomy bag 80, which is not part of the present invention, typically includes a stoma flange 81 with a stoma bag 84 attached to the stoma flange, and wherein a proximal surface of stoma flange 81 is covered with a pressure-sensitive adhesive that adheres to the skin of the abdomen of the patient 99.

The ostomy-bag-cover flange 511 is sized in some embodiments to leave free space 530 between the ostomy-bag-cover flange 511 and the stoma flange 81. Further, in other embodiments of the present invention, a tab 518 is attached to the ostomy-bag-cover flange 511 such that the tab 518 is used to cover and seal the perimeter of the area around the navel 98 of the patient 99 when the stoma is located near the navel such that ostomy-bag-cover flange 511 may not adequately seal all of the perimeter of the area around the ostomy bag 80 due to the uneven surface of the skin in the proximity of the navel. If not needed, the ostomy-bag-cover tab 518 can be removed, either by cutting it off, or in some embodiments, torn off along perforations at the connection of the tab and the ostomy-cover flange 511. The ostomy-bag cover 500 keeps water away from the ostomy bag 80 so that in some embodiments, the patient can swim or engage in other water related activities, shower or bathe, without getting his or her ostomy bag wet. In some embodiments, the ostomy-bag cover is single-use, and is removed and disposed of after use.

In some embodiments, the flexible water resistant plastic film cover 516 includes a watertight, one-way, exhaust vent 517 through which any air or other gases inside of the sealed ostomy-bag cover can be removed without the without requiring the patient to remove the ostomy-bag cover, commonly known as “burping” the cover. This makes the ostomy-bag cover less buoyant in water and improves the patient's experience of swimming or participating in other water related activities while wearing an ostomy bag and ostomy-bag cover. In other embodiments, the flexible water resistant plastic film cover 516 includes a resealable opening 514, through which the ostomy bag 80 can be emptied without removing the ostomy-bag cover. When sealed, the resealable opening 514 is watertight so that the ostomy-bag cover provides a watertight cover for the ostomy bag. The resealable opening can be fastened shut using any one of a number of commercially available resealable closures including ziplock plastic bag zipper-style closures, Velcro® closures, and clips or other fasteners.

FIG. 6A is a front perspective view, and FIG. 6B is a side perspective view, of an ostomy-bag cover system 600, according to other embodiments of the present invention. An ostomy bag 80 is any of several commercially available ostomy bags, wherein the ostomy bag typically comprises a stoma bag 82 which collects patient 99 human waste emitted from the stoma, wherein the stoma bag 82 is attached to the stoma flange 81 and wherein the stoma flange 82 attaches to the abdomen of the patient 99 with an adhesive located on the proximal surface of the stoma flange 81. The ostomy-bag cover 600 includes a flange 611 and a liquid-impermeable flexible cover 616.

In some embodiments, the ostomy-bag-cover flange 611 includes an inner region 612 and an outer region 613, wherein the flange inner region 612 is attached to the liquid-impermeable flexible cover and the proximal (patient-skin) side of the ostomy-bag-cover flange 611 is coated with an adhesive that releasably fastens the ostomy-bag cover to the abdominal skin of the patient 99. The ostomy-bag cover when attached to the patient forms a substantially watertight covering over the ostomy bag 80. In some embodiments, the ostomy-bag-cover flange 611 is of a size that when attached to a patient, some free space (uncovered skin) 630 exists between the ostomy-bag-cover flange 611 and the stoma flange 81.

In some embodiments, the liquid-impermeable flexible cover 616 includes a watertight, one-way, exhaust vent 617 through which any air or other gases inside of the sealed ostomy-bag cover can be removed without the without requiring the patient to remove the ostomy-bag cover, commonly known as “burping” the cover. This makes the ostomy-bag cover less buoyant in water and improves the patient's experience of swimming or participating in other water related activities while wearing an ostomy bag and ostomy-bag cover. In other embodiments, the liquid-impermeable flexible cover 616 includes a resealable opening 614, through which the ostomy bag 80 can be emptied without removing the ostomy-bag cover. When sealed, the resealable opening 614 is watertight so that the ostomy-bag cover provides a watertight cover for the ostomy bag.
